Effects of Yupingfeng polysaccharide in diet on slaughtering performance and meat flavor of Qingyuan partridge chicken

Abstract

With the improvement of living standards, people's expectations for chickens' quality and flavor have also grown. Yupingfeng polysaccharide (YPF-P) has pharmacological effects such as regulating fatty acid composition and gut microbiota. In this study, different doses of YPF-P were added to the feed of qingyuan partridge chickens. The results showed that 8 g/kg YPF-P increased thigh muscle yield by 16.8 % and improved chicken breast flavor by elevating its pH1h and protein content, thereby enhancing flavor richness by 17.16 %.The non-targeted metabolomics (LC-MS) analysis of chicken breast revealed significant enrichment in Arachidonic acid metabolism. Correlation analysis showed the results of LC-MS are significantly correlated with flavor, protein and fat content. Taken together, YPF-P could provide better taste by changing muscle metabolism and increasing the deposition of beneficial compounds in muscle. This study provides valuable insights into the impact of YPF-P as feed additive on the meat flavor quality of poultry.
